PEARL P. REYNOLDS AND JERRY J. REYNOLDS, OF. LAPORTE, TEXAS.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 71 1,346, dated October14, 1902.

Application iiled April 3, 1902. Serial No. 101,250. (No model.)

To all whom. it may concern.:

Be it known that we, PEARL P. REYNOLDS and JERRY J. REYNOLDS, citizensof the United States, residing at Laporte, in the county of Harris andState of Texas, have invented certain new and useful Improvements inAcetyleneGasGenerating Machines; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The invention relates to acetylene-gas-generating machines.

The object of the invention is to provide a machine of this characterwhich shall combine within one single device both a generator and agasometer the parts of which are so arranged as to render the machineefcient and entirely automatic in action, as well as inexpensive ofproduction.

With this and other` objects in view the in- Vention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully explained, and particularly pointedout in the appended claim.

In the accompanying drawings, Figure 1 is a longitudinal verticalsectional view of our improved acetylene-gas-generating machine; andFig. 2 is a longitudinal sectional view of the valve, showing it in openposition.

Referring to the drawings, l denotes a casing having secured to it asurrounding shell 2 and being provided at its upper end with apertures3.

4 denotes a bell or dome of greater diameter than the casing and whichsurrounds the upper end thereof and has its lower end in a seal formedby said casing 1 and the shell 2. The upper end of the bell or dome isprovided with a conical carbid-holder 5, which is provided with afilling-aperture 6, closed by a nozzle 7 with a handle S. The lower endof this holder is provided with a cylindrical valve-casing 10, the lowerend of which projects from the apex of the carbid-holder and the portionof which above the apex of the carbid-holder is formed withdischarge-apertures 11, through which the carbid from the hopper isadapted to escape and be discharged from the lower end of the casing. Avalve 12 works within the valve-casin g and is provided with a stem 13,to which is secured two stops 14 and 15, the former of which coacts witha clip 16, secured to the lower end of the valvecasing, whereby whensaid valve-casing is elevated, due to the pressure of the gas within thedome or bell, said valve will also be elevated and be in position toclose the openings 11. The stop 15 coacts with the crossbar or spider17, whereby uponthe lowering of the bell or dome said stop 15, coming incontact with the cross-bar, will hold the valve 12 against downwardmovement, and as the bell continues to lower the openings 11 of thevalve-casing will be uncovered, thus allowing the calcium carbid toescape from the carbidholder into the valve-casing and into the water.It will be observed that when the carbid-holder is lowered to a positionwhere it abuts against the upper end of the casing 1 and the valve isopened the fresh gas generated will rise and a part will press upwardlyagainst the lower end of the carbid-holder, while the other part,escaping through the apertures 3, will equalize the pressure, and thusprevent the flickering of the light due to an unsteady upward movementof the bell.

18 denotes a draw-olf cock for cleaning the bottom of the casing 1.

19 denotes a service-pipe, and 2O denotes a gage. The gage is secured tothe casing 1 and consists of a tube the lower end of which communicateswith said casing and contains a oat 22, which indicates the amount ofwater within the casing.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of the invention will be readily understood without requiringan extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described our invention,what we claim, and desire to secureby Letters Patent, is-

The combination with a gas-generating casing, of a bell or dome having asealed movable connection with the casing, a carbidholder carried by thebell or dome and pro- IOO jeoting downwardly into the generating-casingand provided with a vertically-projecting cylindrical valve-easinghaving an opening in its side communicating with the carbidholder andopen at its lower end, a clip secured to the lower open end of saidvalveoasing, a valve located in said valve-casing and adapted toregulate the flow of carbid through said opening, a rod fixed to saidvalve and provided with stops, one arranged above the other, across-piece secured in 'the generating-casing, the upper stop adapted tocoact with the Clip and the lower stop to be actuated by thecross-piece, whereby in the I5 upward movement of the bell or dome, the
